Step #2: Attach Tentacles

Take the plastic bubble and glue your ribbon tentacles to the clear top section.

Make sure not to glue the top and bottom of the bubble together - you'll want to be able to open it up and place your throwie in later on. I drew a line to help keep my tentacles even and out of the way.

Step #3: Sew the body

Place your batting, centered, on top of the 2 pieces of fabric. Fold the fabric over the batting and pin.

With a needle and thread, sew through your layers of fabric and batting ~ 1/4" from the edge of your overlap. Be careful not to do any back stitching. When you are finished, pull the thread to gather the fabric and make a scrunchy jellyfish shape (do not knot or tie off just yet).

Step #5: Get those LEDs ready

Take your LEDs and use a pair of pliers to bend the leads at right angles, with the anode (longer lead) on "top." This will give you more space inside the bubble and also point the light upwards. Leave ~1/8" space between the leads, just enough to slide the battery between them.

Add a drop of hot glue between/around the leads before the bend to make sure they don't accidentally touch.

Step #7: Assemble the jelly

Your final magnet will attach to the bottom of the plastic bubble and hold your throwie in place. Make sure it is oriented the right way before gluing by testing it out on the bottom of the throwie "pile."

Hot-glue the magnet to the center of the inside of the plastic bubble and place your throwie on top. Then just snap the top of the bubble back on and enjoy!

At this point you can add some finishing touches; maybe some embroidery or a happy face. I separated the strands of my ribbon tentacles to get more of the wispy/stringy look. You can also try out different combinations of LED colors and plastic bubbles.

Although these are throwies, the plastic bubbles are pretty brittle. I don't recommend tossing them at things. I had a few bounce off surfaces and break when the magnet didn't catch.
